We enable verbose build output in the try_compile of the simple project.
This makes valuable information available in the case of failure.

We need to do this KWSys configuration test in the CMake bootstrap
script to create a proper cmsys/Configure.hxx file.  This fixes the
bootstrap script which was broken by the addition of the test to KWSys.

The 'binary' openmode does not exist on all compilers.  We define macro
<kwsys>_ios_binary, where <kwsys> is the KWSys namespace, to refer to
std::ios::binary if it exists and 0 otherwise.  Sample usage:

  kwsys_ios::ifstream fin(fn, kwsys_ios::ios::in | kwsys_ios_binary);

ENH: refactored ctest.  All testing is now parallel.  If no -j option is specified, defaults to a MP level of 1 (non parallel)

Fixed HDF5 Find module error that caused no list to be passed into remove duplicates when HDF5 is not found.

In cmComputeLinkInformation::Compute we add implicit link information
from languages other than the linker language to the end of the link
line.  This factors out that code into separate methods to improve
readability and organization.

This removes the QUIET option from FortranCInterface_VERIFY in the
Fortran test to really test the detected interface everywhere.

This global property disallows cycles in the inter-target dependency
graph even among STATIC libraries.  See issue #9444.

This function builds a simple test project using a combination of
Fortran and C (and optionally C++) to verify that the compilers are
compatible.  The idea is to help projects report very early to users
that the compilers specified cannot mix languages.

We split the main detection logic into a Detect.cmake support module and
load it only when detection results are not already available.  This
allows results computed by the main project to be used in try-compile
projects without recomputing them.  The call to try_compile() need only
to pass FortranCInterface_BINARY_DIR through the CMAKE_FLAGS option.

This moves platform-independent SunPro compiler flags into separate
"Compiler/SunPro-<lang>.cmake" modules.  Platform-specific flags are
left untouched.

This moves platform-independent Intel compiler flags into separate
"Compiler/Intel-<lang>.cmake" modules.  Platform-specific flags are
left untouched.

This module requires both C and Fortran to be enabled, so error-out if
they are not.
